Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...

Improved Design Procedure for Shallow-Buried Structures to Resist Airblast Loading
Both conventional and nuclear weapons generate airblast loads of sufficient magnitude that structure survival at acceptable cost favors below grade construction. The design of shallow-buried...

Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...

Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...

Multiple Bolt Row Moment End-Plates
This paper presents a portion of the results of a study to develop design procedures for the extended, multiple row, moment end-plate configuration. This configuration is used in steel...

Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...

On Steel Connection Data Bank at Purdue University
The aim of the establishment of the steel beam-to-column connection data bank program at Purdue University in 1986 was to provide the necessary data base for the determination of the moment-rotation...

Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...

Dynamic Fracture Toughness of Rail Steels
As new premium alloy rail steels exhibit increased wear resistance and as track lubrication is used, the failure mode for rails is shifting from wear to fatigue. Elastodynamic finite element...

Thin Precast Fiber Reinforced Cement Panels
This paper provides an overview of some current applications, manufacturing methods, and physical properties of thin fiber reinforced cement board products currently produced. Many of...

Chemical Admixtures for Concrete, What is in Them for the Structural Engineer?
The paper summarizes the effect of admixtures on the economy in construction of concrete structures, on their strength, and on their durability under a variety of service conditions. As...

High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...

Large Reinforced Concrete Active Reclaim Silos
The design and construction of large reinforced concrete shell silos used to provide economical short-term protected storage for coal and lignite in the active reclaim systems of power...

Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...

Projectile Penetration Into Reinforced Concrete and Steel Targets
This paper presents brief preliminary results of a research program sponsored by the Air Force Weapons Laboratory (AFWL) to investigate the interaction of 30-mm cannon projectiles with...

Engineers in Court
Engineers who like debating often serve as expert witnesses. Though many avoid forensic work because they find lawyers intimidating, some like the challenge of explaining engineering principles...

Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...

GTRAF: The Netsim Graphics System
This paper describes the development of an interactive computer graphics (ICG) system, named GTRAF, which will provide users with a new and highly efficient methodology for analyzing results...

Development of Graphics Displays for the Integrated Traffic Data System
This paper describes the development of interactive graphics displays for the Integrated Traffic Data System (ITDS) and provides technical details on the hardware and software considerations...
